RT8058AGQW

RT8058 1MHz, 2A, High Efficiency PWM Step-Down DC/DC Converter General Description Features The RT8058 is a current mode PWM step-down converter. The chip is ideal for fixed frequency and low ripple applications over full range of load conditions. Its input z 0.6V Reference Allows Low Output Voltage z voltage range is from 2.6V to 5.5V with a constant 1MHz switching frequency that allows it to adopt tiny, low cost capacitors and inductors with 2mm or less in height making it ideal for single-cell Li-lon/polymer battery applications. The low on resistance internal MOSFET can achieve high efficiency without the need of external schottky diodes in wide operating ranges and the output voltage is adjustable from 0.6V to 5V that can provide up to 2A load current. The RT8058 operates at 100% duty cycle for low dropout operation that extends battery life in portable devices. z The RT8058 is available in a WQFN-16L 3x3 package. z Low Dropout Operation : 100% Duty Cycle 2A Load Current
